Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526418, here are decompositions:

31 + 526387 = 526418
37 + 526381 = 526418
127 + 526291 = 526418
229 + 526189 = 526418
331 + 526087 = 526418
349 + 526069 = 526418
367 + 526051 = 526418
439 + 525979 = 526418

Showing the first eight; more decompositions exist.
